Application :nea December s, 1921. semi No. 520,092.

To all wlwm it may concern:

v Be it known that I, Or'ro SCHAUMBERG, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Hair- Waving Apparatus, of whichthe following is a specification.

This invention relates to an electrically heated hair waving apparatus, and has for its object to provide, in a manner as hereinafter set forth, a simple and durable hair waver by theuse of which inexperienced persons can readily and expeditiously give to their hair a smooth wave-like shape,

v walls of the corrugated base, which base is constantly heated by the electric heating element. f l

To .the accomplishment of the above mentioned objects and such other objects as `may hereinafter appear, the invention consists of the novel construction, combination, and arfrangement of parts herein specifically Vdescribed, and illustrated in the accompanying drawing wherein is shown `an embodiment of the invention, but it is to be understood that changes, variations, and modifications may be resorted to which come within the scope of the claims hereunto appended.

In the drawing forming a portion of this specification and wherein like numeralsof y.reference designate corresponding parts throughout the several views Figure 1 is a side view ofan electric hair waving'apparatus in accordance with the invention and with'portions thereof shown in cross section.

Figures 2 and 3 are respectively top and bottom plan views of the device.

Figure 4 is a sectional view on line IV-IV,

vof the base.

'as desired.

W-shape and which is formed to provide a pair of longitudinal and parallelly extending inverted V-shaped grooves 2 on the outer face of the base, and a longitudinal V-shaped groove 4 centrally disposed on the inner face A suitable metal cover 5 engages the side walls of the base 1, as clearly shown in Figure 4, and in conjunction with the base 1 forms a completely enclosed chamber 6. The assembly of the cover 5 with the base l may be made The electric heating element 7 is mounted to extend in the groove 4.01:' the base, and

comprises a core 8 of refractory material lupon which the resistance heating coil 9 is wound. -The core 8 is connected to and rigidly supported in position by the terminal block 10, which latter is ixedly clamped, as at 11, upon the rear end of the base 1 upon connect with the feed wires 14 adapted to transmit the electrical energy.

The entire inner wall of the chamber 6 is covered with suitable insulating materials 15. The arrangement of the latter andthe position of the coil 9 will permit of the base 1 intensely heating while the coil 9 is functionlng, and prevent and retard the transmission of the heat to the cover 5.

, A metallic fork consisting of two forwardly projecting tines or ,prongs 16 is plvotally connected, as at 17, by its shank along in and is fixedly secured to the bottom of the groove 4 of the base 1. The Shanks l18 and 19 are respectively provided with handles 20 and 21, at their rear ends. The prongs 16 are curved longitudinally.

The pivotal connection Yof the shank 18 with the shank 19 is such that when the handles 20 and 21 are drawn toward each other bythe hand of the'operator, a prong 16 of the fork will'be positioned to provide a 'pressure action towards and against the bottom of each of the grooves 2 of the base 1. When the-handles 20 land 21 are moved away from each other the prongs 16 will entirely clear the base 1. In otherwords, the pivotal connection 17 permits of a. scissor like motion shifting the prongs 16 into and out of engagement with'respective grooves 2 formed in the base 1.

The base, 1 and associated parts am permanent or detachable `its assembly with the cover 5. The terminals 12 of the coil 9 extend through insulated lapertures 13 in the terminal block 10 and k18, to the shank 19, which latter extends curved longitudinally, as at 22, to conform, as nearly as possible, to the mean curvature of the contour of the human head against which the device is adapted to operate. The lower edges of the side walls of the base l are flared outwardly, as at 23, to eliminate possibility of offensive sen. sations concomitant in the use of the apparatus when in contact with the head.

In practice the basel is heated for a brief period by energizing the coil 9 before applying the device to the hair. The fork member, in the open position, may be readily inserted in the hair, and by drawing handles 20 and 2l together the hair on the fork member will be engaged and forced into the grooves 2 of the now heated base l and held under pressure for a short time, thereby forming a lasting wave-like shape to the hair thus engaged, conforming to the contour of the corrugated base.

What I claim is- 1. An electric hair waving apparatus comprising a base formed with an inner V-shaped corrugation and a pair of outer corrugations disposed in parallelism and each of inverted V-shape, a heating element supported at one end from one end of the base'and extending lengthwise of the inner corrugation, and a fork element shiftable into and out 0f the outer corrugations of the base.

2. An electric hair waving. apparatus comprising a base formed with a V-shaped inner and a pair or inverted Vl-shaped outer corrugations, a `heating element mounted within the inner corrugation, a fork element shiftable into and out of the outer corrugations of the base, and a cover engaging the outer walls of the outer corrugations and enclosing the heating elementa 3. An electrical hair waving apparatus comprising a W-shap'ed base curved longitudinally, said base formed with a pair of longitudinal parallel grooves on its outer face and with a longitudinal groove on its inner Y face disposed centrally with respect to the said pair of grooves, a terminal block positioned at the rear end of the base and supporting a heating element at one end of the latter, said heating element extending lengthwise of said groove on the inner face of the hase, a cover mounted on the base enclosingl the heating element and adapted for clamping said terminal block on said base, a fork element including a pair of prongs said :fork shiftable to osition one of said pair of prongs into an out of each of said air of outer grooves, said pair of prongs ing curved longitudinally.-
